Alas the weather is often awful in 'Cornwall - but as it's been so ghastly most places in England this year you might find it an improvement. You mentioned the Eden project. I used to have a season ticket and drag all my visitors there. I haven't been for a couple of years, but I think it's wonderful. I hope you get to see it. I'm not too fond of Newquay itself, but there's lots of lovely places near at hand and the Underwater place (can't remember its name) is good. I used to live at Porthtowan which is fairly near but only small.
